PTP Procedure Statements Summary
The protocol identifier refers to the protocol that you set. X25AM does not save the
incoming (remote) protocol ID.
SETPARAM 9
Get the reason for the disconnection of the circuit.
Table 3-11 lists the numeric values returned in the reason buffer for SETPARAM 9.
CALL SETPARAM (filenum, operation,,, reason, length)
filenum = file number
operation = 9
reason
= 4 words. For reasons for call disconnection,
see Table 3-11.
length = 8 (the length in bytes of the reason
parameter)
Table 3-11. Reasons for Circuit Disconnection (SETPARAM 9) (page 1 of 2)
Integer Reason for Circuit Disconnection
Integer <0>
0 Never connected.
1 Still connected or connecting.
2 CONTROL 12 issued.
3 Subdevice file closed.
